Whatsapp is a true cross platform messenger application that is available on Android, BlackBerry, iOS and Windows Phone. The messenger allows users to send texts and files amongst friends across different platforms. And alongside instant messaging, Whatsapp also allows sharing of photos, videos, audio and your location with other users. It all makes absolute sense for the users to have this app to stay connected to most friends and to discover new ones too.
The most convenient part of this app is that it uses the phone number of the user as identity so that users need not go through a lengthy registration process. Whatsapp sends messages through the internet; hence SMS charges are not applicable. The messaging app scans users address book when they sign in for the first time, and tells them which of their friends is using Whatsapp by syncing its databases along with them.
The application comes free of cost for the first year and following that users need to pay $1.99 or Rs 100 approximately year on year for services which makes absolute sense.
